CAN-FILLING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 527,982, datedOctoberl23, .1894,

H Application filed August 12, 1893. Serial No. 482,964. (No model.)

' provements are: first, to provide a device by which the valve will beautomatically opened by the simple act of placing the apparatus in thecan or receptacle; second, to so connect the valve opening mechanismwith the float that the incoming liquid on reaching the required levelwill raise the float and trip the valve automatically; third, to insurethe valve closing positively and quickly (not wiredrawing the liquid);fourth, after being tripped to leave the valve entirely free from theopening and closing mechanism, so that it can seat itself properly;fifth, to simplify the apparatus by combining the opening and closingmechanism in one device, and to have no exposed working parts. I attainthese obj ects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1. is a view of the entire apparatus. Fig. 2.is a vertical section of the enlargement of the main pipe at its lowerend.

Similarlettersrefer tosimilarpartsthroughout both the views.

The apparatus consists of a pipe A. to the lower end of which is screwedthe enlargement B. The upper end of pipe is connected by a hose with thesupply of liquid. A water-tight float O surrounds the pipe, and thisfloat is free to move up or down. The float is surrounded by a guard Dwhich prevents it being injured when the apparatus is laid.

on thefloor. This guard is adjustable verti cally and is secured by aset-screw. Between the guard D and valve enlargement Bis fixed atube E,which protects from injury the wire F, which connects the float with thetripping lever G. The enlarged portion B contains a valve H which isfree to move vertically, and is guided by the stems I K passing throughspiders L M. The valve H rests normally on its beveled seat N, withwhich it makes a wator-tight joint. The lower end of the enlargement isprovided with a nozzle 0 having side openings P P. The nozzle 0 carriesa spindle R, which is free to move vertically. This spindle projectsthrough a hole in the extreme bottom end of the nozzle, and the top endof spindle passes through and is guided by the spider S. Around thespindle R is coiled a light spring T which bears against the under sideof spider S, and a pin on spindle R, thus tending to keep the spindledown. The upper end of the spindle R is enlarged and forms a hinge jointV, to which is hinged the tripping lever G. At the outer end the lever Gterminates in a finger X, which passes through a loop Y formed on thebottom end of the float wire F. From the of the apparatus continues ondown until the end of the nozzle 0 rests on the bottom. During thisdownward movement the valve stem K impinges on the pin Z and stops. Theseat N, together with the balance of the apparatus, continues on downand leaves the valve H, thus allowing the liquid to pour down and out atopenings P P. The play of the loop Y allows a free downward movement ofthe wire F. The liquid rises in the can and reaches the float C, whichgradually rises and lifts the wire F until the lost motion of the loop Yis taken up, when the lever G is revolved onits axis V, therebydisengaging the pin Z from the valve stem K at any desired level of theliquid, depending on the position of float O. The disengaging of the pinZ allows the valve H to fall and shut off the flow of liquid. Theapparatus may .remain in this position for any length of time withoutallowing any more liquid to flow into the can.

When the apparatus is removed from the can the spindle R is forced downby the spring T, and as soon as float 0 leaves the liquid, the floatwire F and lover G immediately regain their normal positions and theapparatus is ready to be used again.

I am aware that prior to my invention canfillers have been made, withfloats, projecting valve stems, and valve tripping devices. I thereforedo not claim these combinations broadly. Also there are can-fillers inwhich the valve is raised by a projecting stem, but the valve is closednot by being tripped, but by the whole apparatus being lifted by a largefloat, thus raising the valve seat slowly against the valve, thuswiredrawing the flow of liquid.

What I do claim as my invention, and desire to secure by Letters Patent,is

1. In a can filler the combination of a valve, a valve supporting pieceplaced under the valve, constructed and arranged to trip said valve, anda contact piece projecting through the lower end of the water pipe andarranged to automatically raise said supporting piece.

2. In a can .filler the combination of a valve, provided with adownwardly projecting valve stem, an automatic contact piece and a leverpivoted to said contact piece and constructed and arranged toautomatically raise and trip the valve.

3. In a can filler the combination of a main pipe A, enlargement B,automatic contact piece R, lever G (pivoted to said contact piece andadapted to automatically raise and trip the valve), valve PL'connectingrod F, float O, and guard D, substantially as shown and described.

4. In a can filler the combination of a valve, an automatic contactpiece projecting through the lower end of the water pipe and anintermediate valve raising and tripping lever provided with means fortripping the valve, said valve and lever being contained entirely withinand protected by the Water tube.
